Medications administered intravenously have the potential to escape from the venous circulation and filter into the surrounding tissue, which may cause infiltration or extravasation.
Infiltration consists of the leakage of irritants, which leads to inflammation and pain, but without producing tissue necrosis.
 The appearance of extravasation can lead to severe tissue damage, which may require surgical debridement and skin grafting, prolongation of hospital stay, and increased morbidity.
